    libdocument: deprecate ev_document_misc_get_screen_dpi()
    
    The GDK screen size functions, such as gdk_screen_get_width(), are
    deprecated since GDK version 3.22 in favor of the per-monitor
    information provided through GdkMonitor. In turn, deprecate evince's
    ev_document_misc_get_screen_dpi() function in favor of
    ev_document_misc_get_widget_dpi(), which uses the GdkMonitor API.
